+The pdfTeX team is happy to announce the release of a new stable version:
+
+===========================================================================
+ pdfTeX 1.40.0
+===========================================================================
+
+This is the announcement of pdfTeX 1.40.0, an extended version of TeX that
+can create PDF directly from TeX source files and enhance the result of TeX
+typesetting with the help of PDF.
+
+===========================================================================
+ Main changes of pdfTeX 1.40.0
+===========================================================================
+
+- pdfetex (as a separate binary/program) is gone; all extensions are now in
+ pdftex. The make files still know about the target pdfetex, but it's just
+ a copy of pdftex
+- The sources of TeX, eTeX and pdfTeX have been merged into one file
+ pdftex.web and one change file pdftex.ch. The sources of TeX and eTeX
+ distributed are just there for reference
+- New features:
+ - pdfTeX can now generate PDF 1.5 object streams, which leads to smaller
+ PDFs. This is controlled by setting \pdfobjcompresslevel to a value >0
+ (3 compress everything, 2 don't compress /Info, 1 also don't compress
+ embedded PDFs) and works only with PDF >=1.5
+ - pdfTeX now supports another image file format: JBIG2 files (.jbig2)
+ - the memory allocated for objects and destination names now grows
+ dynamically
+ - pdfTeX now generates smaller PDFs since for char positioning the width
+ of chars (/Widths) is stored with more precision and so the chars must
+ rarely be positioned separately
+ - the PK resolution is now taken from the "pk_dpi" parameter in texmf.cnf
+ if it has not been set in the format file or by the user
+ - pdfTeX now removes the generated pdf in case of a fatal error
+ - pdfTeX now sets /ModDate and /Trapped in the InfoDict by default (the
+ values can be overridden with \pdfinfo)
+ - the format of warnings and errors issued by pdfTeX has been changed and
+ unified
+ - the output of -version has been extended and now includes information
+ about the libraries actually used, which can be handy when using shared
+ libraries
+ - rules and their positioning on the page are now inside a qQ group
+- New primitives:
+ - pdfTeX can now handle colourstacks.
+ - \pdfcolorstackinit
+ A stack is initialized by \pdfcolorstackinit. It expands to the
+ number of the new stack. The common case, the traditinal color stack
+ is already initialized as first stack: \pdfcolorstackinit page direct
+ {0 g 0 G} The keyword "page" means that this stack is page based. At
+ the start of the new page, the current stack value is automatically
+ set.
+ - \pdfcolorstack
+ \pdfcolorstack <stack number> push {<new color>}
+ pushes the current value on the stack and sets the <new color>.
+ \pdfcolorstack <stack number> pop
+ pops and sets the current stack value.
+ \pdfcolorstack <stack number> current
+ sets the current stack value without changing the stack. This is
+ useful for stacks that are initialized without keyword "page". Thus
+ the page start setting can be set manually.
+ \pdfcolorstack <stack number> set {<new color>}
+ The current value is set to <new color>.
+ - Transformation matrices can now be manipulated more cleanly:
+ Currently matrix changes are done and hidden inside \pdfliteral nodes;
+ pdfTeX doesn't parse its contents and does not know the new settings of
+ the transform matrix. Thus the new primitives to save pdfTeX from
+ parsing \pdfliteral contents and to notify pdfTeX about matrix changes
+ to use them in calculating link and anchor positions.
+ - \pdfsetmatrix{<a> <b> <c> <d>}
+ is the equivalent to \pdfliteral{<a> <b> <c> <d> 0 0 cm}
+ - \pdfsave is the equivalent to \pdfliteral{q}
+ - \pdfrestore is the equivalent to \pdfliteral{Q}
+ - \pdfprimitive\TeX-primitive executes the original \TeX-primitive even
+ if the command has been redefined since. E.g.
+ \let\relax\undefined\pdfprimitive\relax
+ expands to \relax.
+ \ifpdfprimitive\TeX-primitive is true if \TeX-primitive has its
+ original meaning
+ - \ifpdfabsnum and \ifpdfabsdim are like \ifnum and \ifdim, but don't
+ care about negative numbers
+ - shell escape: if the first character of a filename for \openin,
+ \openout \input is a pipe symbol (|), the filename is assumed to be a
+ request for a pipe to a command line that is given in the rest of the
+ filename
+ - draftmode: With \pdfdraftmode=1 or the commandline switch -draftmode
+ pdfTeX doesn't write the output pdf and doesn't actually read any
+ images, thus speeding up compilations when you know you need an extra
+ run but don't care about the output, e.g. just to get the BibTeX
+ references right
+ - \pdfpxdimen (introduced in 1.30) is now a real dimension parameter. It
+ allows one base dimensions on pixels. 1px defaults to 1bp (or 72dpi),
+ but can be changed with the \pdfpxdimen primitive:
+ \pdfpxdimen=1in % 1 dpi
+ \divide\pdfpxdimen by 96 % 96 dpi
+ \hsize=1200px
+ Now \hsize is (1in/96)*1200
+ - \pdflastlink returns the object number of the last \pdfstartlink
+ - \pdfsavepos now works in DVI mode
+- Fonts:
+ - support for subfonts: This creates all needed map entries for subfonts
+ automatically and handles Unicode mappings
+ - ToUnicode entries for Type1 fonts (patch 580)
+- HZ:
+ - added patch 462: HZ font expansion in autoexpand mode now produces
+ smaller pdf files, as it works by modififying the text matrix for
+ single fonts instead of embedding many expanded font versions.
+ Therefore HZ now can be used also for TrueType fonts and even for
+ non-embedded fonts (e.g. Times-Roman)
+- Bugfixes:
+ - the PDF statistics in the log are now correct
+ - added JFIF detection patch to writejpg.c (bug 548)
+ - bugfix: invalid pdf created if font name contains space (509)
+ - bugfix: truetype OS/2 v3 fonts (594)
+ - bugfix: Type1C (CFF) fonts of embedded pdfs didn't get replaced
